Remove extra points in export to SVG
Remove the Sampling modifier from the Geometry modifier stack.

This modifier adds extra stroke vertices at a regular interval.  This modifier is added by default because it is necessary in many stylization situations, e.g., when you want variable color, alpha transparency and/or line thickness along stroke, and when you want to add distortion to stroke geometry.  If you don't need the extra points, you can just remove the modifier.
